Great to hear. Would having a WIFI connection thru my iPhone enhance positioning?

Don't think so, you can use GSM to enhance positioning but the information is not re-delivered using personal hotspot. I don't have experience with iPad and Navigation but using an iPhone 3GS and an iPhone 4 I didn't have problems.
